Space Station Toilet Breaks

That's a real crapper.

The main toilet aboard the International Space Station has broken down, forcing the three crew members to use the loo on the Soyuz escape craft that's permanently attached to the ISS, according to various media reports.

However, the Soyuz head will offer only temporary relief, as its holding tank will quickly fill up.

With all the thought put into redundancies on the space station, nobody thought about the possibility of toilet failure?
